just go to a part store like schucks and have them read the trouble codes and erase the check engine light by their OBD code reader which they give it out for free and even help you use it if you have no idea how to.
Replace the remotes battery
If you disconnect without turning off the charger, the sparks caused may ignite the hydrogen discharged from the battery while charging.
The easiest way to reset a service lamp on any vehicle is to disconnect both battery terminals first. Run a wire across both battery terminals and leave attached for at least a couple of hours. Detach the wire and reconnect the battery terminals. Your service light should now be out. Make sure that you do not run the wire across the positive and negative terminals of the battery. Make sure you disconnect both terminals and run the wire across the cables and not the actual battery terminals. If your service engine light is on it means your computer is registering a code. Make sure you take your car to have it diagnosed properly instead of resetting the light. It may be a serious code that could cause problems in the future.
Check earth connection. Sometimes if wires aren't connected right, running the car will discharge the battery instead of charging it... ----------------------------------------- Check for a current draw by disconnecting the negative cable at the battery and hook a test light between the cable and the battery. Remove fuses until the light goes out. While doing so remember to depress the door jam switch as it will show a current draw.
Yes
Sounds like your battery was weak to start with. What you did should not have caused any problems if your battery was in good condition so without seeing it, I think you should remove your battery and have your battery charged and load tested.
No, not unless you installed a 6 volt battery instead of a 12 volt battery.

If the light is still on then the problem was not the battery but was instead the alternator which is more than likely defective.
This is a safety precaution. Disconnecting the ground cable protects you from accidental shocks, accidental engine starts (by someone unaware of your presence underneath, perhaps), in airbag equipped vehicles it prevents the airbag from deploying accidentally (expensive and/or injurious). Obviously, if the repairs in question require that battery power be available, you wouldn't disconnect it, but the protection it offers is well worth the extra minute it takes to disconnect the cable. As far as why the negative instead of the positive cable is disconnected, the reason is that if you are touching the positive cable and anywhere else on the vehicle, you'll get shocked. Not so, with the negative cable. Also, the negative cable seems less prone to sparking than the positive cable. If, however, you are working on a vehicle with positive ground (uncommon in North America), the positive (ground) cable is to be disconnected
If it will physically fit in the space, then yes, the 2700 mAh battery should work fine.
Before you start, it is advised that you disconnect the battery otherwise you may blow a fuse. There is a fuse for the bulb which can be removed instead of disconnecting the battery, but I don't know which fuse it is. Remove the cover by gently prying it open using a screwdriver. You'll see two small openings next to the switch, this is where you should insert the screwdriver. Be carefull not to stick in the screwdriver too far or force it open. If it won't open easily then you are doing something wrong. To replace the bulb, simply remove it with your fingers, it should come out easily. Gently insert the new bulb. Be carefull, the bulb is very fragile and may break if forced. Reconnect the battery and test the bulb using the light switch. Snap back in the cover and you are done.
